Reliable and accurate photovoltaic (PV) output power projection is critical for grid security, stability, economic operation. However, because of the indirectness, unpredictability, solar energy volatility, predicting precise reliable a complicated subject. The variable evaluated in this study using powerful machine learning approach called support vector model based on gray-wolf optimization. A vast dataset previously published papers was compiled purpose. Several studies were carried out...
In this paper, we present an empirical statistical model, photovoltaic (PV) power forecast model (SPF) based on the historical and weather type data. Firstly, data is grouped into 4 levels, according to influence of different types penetration rate solar radiation. Secondly, K-means parabolic least square fitting are used PV each level. Thirdly, variations initial fitted further investigated by analyzing probability distribution residuals. The final validated a ten-day for three stations,...
